Lineare Polymerisate von N-(2-(1'-Aziridino)ethyl)formamid, Verfahren zu ihrer Herstellung und ihre Verwendung

摘要

Linear polymers of N-(2-(1'-aziridino)ethyl)formamide obtainable by the polymerisation of N-(2-(1'-ariridino)ethyl)formamide in aqueous or alcoholic solution or in mixtures of water and alcohols at temperatures of up to a maximum of 75 DEG C in the presence of acid catalysts, alkylising agents or Lewis acids, process for the production of the polymers, hydrolysed N-2-(1'-aziridino)ethyl)formamide, from which at least 5 mol % of the formyl groups are separated with formation of amino groups, and the use of the non-hydrolysed and hydrolysed polymers as dewatering agents, retention and flocculants, fixers and wet-strength agents in paper production.
